问2个问题,散分
jsp怎么实现多国语转换。.net我会多国语转换,jsp不会~~
还有就是jsp可以用asp的探针吗?
把asp的探针代码放到jsp页面中能够用吗?
因为这个都是我用.net做出来的,所以想在面试java的时候也说这个项目,所以不知道java中是怎么实现。只要说出大概思路就行,因为这个是我要在面试的时候要讲的,所以只要思想....
------解决方案--------------------jsp有控制验证的功能吗?
有很多方法可以实现,我一般都是用Filter 来实现
可以看看这个http://blog.csdn.net/gnemy/archive/2007/02/04/1501973.aspx
